Sodium-lack contractures by strips of bullfrog ventricle were found to be increased in the presence of manganous ion (1–10 mM). In addition, peak force development was usually attained earlier in the presence of manganous ion and the rate of relaxa

The briefly described theory of an electrostatic fluxrneter (ELV) exposed to the ionospheric plasma permits the determination of ion drift velocity from measured signals. Results of a rocket flight under twilight conditions are reported where electri

Frog atrial muscle strips were placed in a double sucrose gap chamber and perfusion of the central node was arranged as to allow rapid changes of external Ca or Na concentration during long-lasting (15s) depolarizing clamps. When the superfusing flui

A technique has been developed whereby the direction of the plasma wake produced by a sounding rocket is obtained by measuring the electrostatic field at the surface of the vehicle. From the orientation of the wake the direction of ionospheric plasma

The reactions12C(7Li,d) and13C(7Li,t) have been studied atE C.M.=13.3. MeV. Spin assignments have been extracted from the integrated cross sections of the first reaction. The latter reaction has been analysed in terms of a modified-DWBA code.

Two Skylark rockets were launched from the range of the European Space Research Organization (ESRO) near Kiruna on February 14, 1970, at 17.15 CET and on April 2 at 02.46 for investigation of electric fields. Each rocket carried an electric double-pr

Angular distributions of the reaction 12 C( 7 Li, t) 16 O have been measured at E lab = 15, 21.1 and 24 MeV with a magnetic spectrograph and a d E /d x — E telescope. From the shape of the angular distributions and the weak excitation of the 2 −

45Ca washout from ventricles of the bullfrog was followed through an automated technique previously described. Lanthanum decreased the fractional rate of loss of 45Ca (by 67% at the saturating concentration, 1 mM, for this effect of the trivalent cat

Voltage clamp responses of a single excitable fiber were simulated using a core conductor model including a high external resistance (Rs) in series to the fiber membrane to allow for intercellular clefts in a multifiber preparation. In terms of speci

A theoretical model is presented for voltage clamp of a bundle of cylindrical excitable cells in a double sucrose gap. The preparation in the test node is represented by a single one-dimensional cable (length/diameter ratio approximately) with standa
